Explanation

RAID 1 is the mirroring level where data is written identically to two or more disks, providing redundancy. If one disk fails, the other contains an exact copy. RAID 2 uses bit-level striping with Hamming codes, RAID 3 uses byte-level striping with dedicated parity, and RAID 5 uses block-level striping with distributed parity.
